Calculate the overall heat transfer coefficient (u0) based on outer surface of a pipe with outer diameter of 4 cm and inner diameter of 3 cm. Thermal conductivity (K) is 53 W/m°C. Heat transfer coefficient hi and 1/0are 2000 W/m2°C and 1000 W/m2°C. Fouling factors are Fi = 14 x 10-5m2°C/W and F0= 15 x 10-5 m2.
